Anleitung Zusammenfassung


The diagrams in this manual are meant to show the necessary equipment and piping. Your system may look very different. However, if configured properly, the same results will be achieved. Fig. 6 shows a typical plumbing diagram for tying into an existing system. This method provides water circulation between the two boilers with a circulating pump. In this setup, the domestic water coil in the existing boiler will be heated, making it unnecessary to install a water coil in the Trident Boiler. Tying-in to an existing boiler must be done in the return line between the circulator and the existing boiler. Run a pipe from there to a small circulator, and then into the 1-1/4 in. fitting on the rear of the Trident Boiler. Next run a pipe from the 1-1/4 in. fitting on the top of the Trident Boiler to a Tee fitting in the supply line of the existing boiler. This Tee fitting must be installed between the existing boiler and the Flow Control Valve, as shown in Fig. 6. An air valve should be installed on this line also. 3 feet (0.9m) above the point at which they exit from the roof, it must also extend 2 feet (0.6m) above the highest point within a 10 ft. (3m) radius. Do not connect this unit to a chimney flue that is serving another appliance. FIG.5 Limit connector pipe to 8 ft. or less, with no more than two elbows. All horizontal sections should have 1/4 in. rise per foot. The chimney must be capable of providing a draft reading of at least .06 in. of water column. A barometric damper can be installed to prevent excessive and erratic draft. All connector pipe should be secured with sheet metal screws at each joint. Air Valve Notice: The Aquastat controls supplied with the Trident Boiler are designed only to maintain water temperature within the boiler. The actual heating system is controlled separately by your thermostat(s) opening zone valves or energizing circulation pump(s). Do not attach a thermostat to the supplied controls. FIG.6 Installation The circulator installed between the two boilers may be hooked up to run continuously during the heating season or, an additional S350 control (not supplied) could be installed to turn it on and off automatically. This control must be used as a “close on rise of temperature” (jumper in cooling position). Harman Stove Company recommends that 1-1/4 in. pipe be used between the two boilers. Also recommended is that the first section of pipe off of the top of the Trident Boiler be threaded galvanized or threaded black-steel pipe. The Harman Trident Boiler is supplied with a dual function aquastat. The A350 is used to control the automatic draft control whether open, to increase heat, or closed, to decrease heat. The S350 is used as overheat protection. Since a wood or coal fire is still producing heat when the draft is closed, this overheat protection is required. You could have the S350 energize a circulating pump or a zone valve separate from the heating system, or it could be hooked up so that it flows the heated water throughout the system. Either way, it must be able to flow away from the boiler. Figure 7 shows a typical schematic of the Trident boiler as a “stand alone” system. Note; the crossover pipe (#12) is not totally necessary but is recommended to provide circulation within the boiler while the heating system is satisfied. This will ensure an even temperature within the boiler. The tempering valve shown (#10) is to prevent excessive temperature of the domestic water. FIG.7 Operation Starting a Wood Fire Make sure the boiler and all piping is full of water and that all air has been purged from the system. Never start a fire without water in the system. An explosion will occur. Turn on electrical power to the boiler. This should cause the automatic draft control to open. Open the ash pan door to allow free air movement. With the firebox door open, crumble approximately 8 sheets of newspaper and place on the grates. Lay some small kindling on top of the newspaper. Be sure this kindling is dry and no more than 3/4 in. in diameter. Layer the kindling in a criss-cross type pattern, to allow maximum air flow. Next lay some larger pieces of wood on top of the kindling (approximately 2 in. diameter). Using a match or lighter, light the paper just inside the door. Close and latch the firebox door and allow the fire to burn a few minutes. After about five minutes, close the ash pan door and re-open the firebox door an inch or two, to allow the smoke to clear. Add 4 or 5 larger logs (about 4 in. diameter) to the well established fire and close the firebox door. Leave the ash pan door open for about five minutes only. Now open the firebox door using the same method as before, always closing the ash pan door before opening the firebox door. Now you can load the firebox to the desired level. You may load wood to the top of the firebox. Close and latch the door. The ash pan door may again be opened to speed the ignition process. Do not leave the boiler unattended with any door op...
